DISPLAY APPARATUS.

To all whom t may concern Be it known that we, KIHEI Konin and GEOBGE.L..GRANT, subject of the Emperor of Japan and citizen of the United States, respectively, residing at Seattle, in the county of King andA State of Washington, have invented i l the following is a specification.

.lid

Our invention has for one of its objects to provide novel mechanism for advancing slides or Vother means containing display matter to and from afdisplaying position, and further, to generally simplify and im-` prove-display apparatus of this character.

@ther objects will be set'forth as our description progresses and those features of construction, i tions of parts on which we desire protection succinctly defined'in our annexed claims.

Referring tothe accompanying drawings wherein We have shown our invention comfor projecting matter for display on a screen or other suitable surface: Figure 1 is a plan of the device with the cover of the casing, and the lamp chamber removed. Fig.' 2 is a vertical section thereof with atportion of the chamber` for the illuminating means broken away. Fig. 3 is a fragmentary plan ofthe device with the cover of the casing removed. Fi 4 is a fra mentary sectional plan illustrating the driver advanced. Fig. 5 is a detail illustrating more particularly' the switch mechanism. Fig. 6 is a detail perspective of one ofthe slide holders. Fig. 7 is a vertical cross section through the lower portion of the' casing, and Fig. 8 is a fragmentary section taken through the driver on line 8 8 of Fig. 7.

Referringto the drawings by numerals of reference, 1 with a removable to wall or cover 13 and having its side wall fdrmed with an opening 1 over which4 a projector 2, of any suitable or well known type, is secured. i

Reference numeral 3 indicates a slide carrier,th'e same being rotatably mounted on rollers 4, journaled -on stands 57 fixed tothe bottom wall of casing 1.

Reference numeral' indicates guide rollv .ers journaled on the upper end portions of j Specication of Letters Patent. Application filed May 31, 1912.

certain newand useful Imyproveinents in Display Apparatus, of which arrangements and combina-4 the fside portions loined with suitabler projection mechanismindicates a casing provided Serial No. 700,867.

Within carrier 3' and in line with projec- `tor 2, a condenser 7 is provided, this being portion of a mounted in the forward end chamber 8 provided with illuminating means, as for example, an electricilamp 9. 'Chamber 8 is supported on. standards 10 of casing 1. Carrier 3, whichis cylindrical in form is provided in its Wall with openings over which suitable slides 11, bearing the matter for display, are arranged, the said slides be` ing mounted in holders l2. These holders which are secured, asby rivets, to carrier 3 intermediate the openings thereof are in form of guides having their opposite d bent to angular formation to engage adjacent slides 11 andhaving attheir ower portions, inturned lugs 12, `as` more clearly shown in Fi .6. By the construction just described, hol ers of extremely simple construction are provided, and these, as will be observed, permit of the slides 11 being readily inserted or upper portions.

For operating carrier 3 position the slides 1l successively in front of condenser 7, We provide mechanism now to be described. i

Reference numeral 14 vindicates a driver, journaled'on a stub shaft I5, and 16 indicates an engaging member for alternately connecting and releasing `carrier 3 with respect to said driver, the said engaging member 16 being guided in lugs 17 of driver 14 for movement lengthwise thereof, whereby when projected, its outer end portion can engage 1n suitable apertures, as 18, of the carrier., n

Reference numeral 19 indicates -a spring connected to driver 14 and to a fixed lug, as 20, of casing 1, for retracting said driver.

For operating driver 14 in its advance or intermittently to retreated aan. av, i914. e

removed through 'their` active movement, we provide a solenoid 21,

the core 22 of which is provided with an in sulated stem extension 22 whose outer end portion is provided with a shoulder 22 against which a link 23, apertured to freely receive stem 22', is yieldingly held by spring 19. Link 23 is pivoted to a Y-shaped lever former or normal 24, fulcrumed at 24 on casing 1 and having its other arm connected by a link 25 with a depending stud 26 of driverf14.

Reference numeral 27 indicates a setting devicefor engaging member 16, the same being horizontally disposed and fulcrumed, as at 26, substantially centrally of its length, and beneath or at the lower side of the path of driver 14. One end portion of setting device 27 is connected, as by a Hlink 28, to the inner end portion of engaging member 16,

by which construction adjustment of device` 27 serves to project and retract the engaging member.

Reference numeral V29ndicates an actuator for setting device 27, the same comprising an arm having slotted engagement, as at 15', with stub shaft 15, whereby it is free for a limited travel in the direction of its length. The outer end portion of actuator 29 is provided with a bearing member or roller 30 adapted for travel on the inner face of device 27.

Reference numeral 31 indicates a link connection between actuator 29 and driver 14, the same having slotted engagement, as at 31, with' stud 26 to permit of the inward and outward adjustments of actuator 29, as will be readily understood.

A spring 32, connected to fulcrum 26 and to the inner end portion of actuator 29, tends to yieldingly press the latter outwardly.

Reference numeral 33 indicates circuit' wires, connected with a suitable source of electrical energy, not shown, for supplying current to solenoid 21. In one of these wires 33, we provide` a switch comprising a contact 34, and an arm or knife 35, the latter of which is carried by a pivotal support 48, connected by pin 49 with setting device 27.

In the operation of the mechanism thus far described and with the parts in the position shown in Fig. 1, solenoid 21 is energized, and through the inward movement of its core 22, driver 14 will be swung for wardly through the connecting means comprising link 23, lever 24 and link 25. This movement of driver 14 effects, through link 31, a simultaneous advance movementjof actuator 29, and as the latter passes over or beyond fulcrum 26 it will swing setting device 27 to substantially the position shown in Fig. 4 thereby opening switch parts 34, 35 and retractingr engaging member 16. Spring 19 now returns driver 14 to its position, during which movement engaging member 16 is projected and yieldingly held in engagement with carrier 3 through spring 32 until the succeeding aperture 18 is encountered.

To insure'o the proper setting of the slides 11 wit-h respect to projector 2 and condenser 7 a locking device 40 is provided, this conveniently consisting of an outwardly projecting lug on the forward end portion of setting device 27 and adapted to be moved into and out of openings 18.

ReferenceV numeral 41 indicates a gov-v ernor for retarding return movement o driver 14, the same conveniently comprising a plurality vof pliable wings which ca`n be bent -to obtain a greater or less resistance, by the air to their travel. Governor 41 is mounted.. on a vertical shaft '42' provided with a pinion 42 in mesh with a gear 43 of an intermediate shaft 43, which latter is driven by suitable speed increasing gearing 44 from a shaft 45 which latter is provided with a pinion 46 meshing with a segmental rack 47, constituting a fixed extension of driver 14. One of the gears 44 is loosely mounted on shaft 45 and connected therewith through a pawl and ratchet connection 48 through the medium of which shaft 45 communicates movement to gearing 44 only during the backward or return movement of driver 14.

Having thus described our invention what vwe claim as new, and desire to secure by Le-tters Patent ofthe United States ot America,
